To all whom it may concern: shown in detail.

In the centre of the plank is a hole (l8),-and The object of this invention is to provide a cylindrical sack (19) made of waterproof a chair of basket work, to be used in ordimaterial having a hole (20) in it. On the nary times as a seat on board ship, and in under surface of the plank is arranged a 0 case of shipwreck, to serve as a floating signal flag (21) attached to a rod. frame work on the sea to enclose a water- In Fig. 6, i shown the report plank driftproof canvas sack holding a person, the ining on the water.

Thus it willbe seen that the present apparatus may rightly be described as an ideal life preserver, serving both in ordinary times as well as in time ofemergency.

Having thus described my invention,

what I claim as new, and desire to' secure by Letters Patent, is

1. A life preserver comprising a "chair provided with a seat, the portion of the chair arranged beneath the seatlforming a chamber, a water-proof sack normally occupying said chamber and'capable of being opened out to permit a person to occupy buoyant'belt extending arounc ent materlal arranged in said sack, a hoop connected to the sack, means for-fixing said hoop to the chair-back in order to hold said hoop in raised position, and" a ventilating tube fixed to said hoop and adapted to be raised with-the same.- 1

'2. In a life preserver, asack constructed to entirely enclose a person, an open ended flexible tube extending through the wall of the sack and having its outer end opening sack and its inner end within the sack, fastenexteriorly of the portion arranged ing means arranged within the sackand Y said seat while, in case of disaster, it

1 to and discharging air connected to said tube near its inner end for contracting the tube near the last, mentioned end, and other fastening means located within the sack and arranged near the outer end' of the tube for contracting said tube near its outer end.

3. A life preserver as claimed in claim 1 in which the chair is provided with vertical posts, and spring clips arranged on said posts and adapted to support the hoop in raised position.

4:. A life-preserver as claimed in claim 1 in which the ventilating tube iis'provided with a suction pipe and an escape pipe, the upper end at a higher-plane than the upper end of the escape pipe in order to prevent water from entering said sack.

5. A life preserverincluding achair proof the suctionpipe being situated:

vided with a seat, the portion of the chair beneath saidseat forming a storagechamber, buoyant means varranged on the chair for holding the latter in upright position, when the'same is in the water,'a waterproof sack adapted to be stored in said chamber and to be opened out to receivela person, a ventilating tube for furnishingair from the interior of the sack when the latter is opened out, and

means for holding said tube in a fixed plane relatively to said chair.

6. A life-preserver includinga buoyant chair provided with a. water-proof sack adapter to receive a-person, anda separable buoyant seat for said chair provided on one side with alongitudinalifiag and on its opposite side with a sack adaptedto befilled with water for holding the flag upright.
